T0 fall whom, it mfc/y concern:

Be it known that I, WILLIAM C. NORMAN, a citizen of the United States,residing at Smithton, in the county of Clark and State of Arkansas, haveinvented certain new and useful Improvements in Fan Attachments, ofwhich the following is a specification.

My invention is a fan attachment to sewing-machines and mechanism fordriving the same in connection with the band mechanism of the machine;and it consists in a frame attached to the table of a machine providedwith mechanism to run a band-wheel and a band extending to theband-wheel of. the fan.

1n the accompanying drawings, Figure 1 is a rear elevation of ahigh-armsewing-machine with my invention attached thereto. Fig. 2 is an end viewof Fig. 1.` Fig. 3 is a detail view showing an elbow-arm and a clamp forsecuring the same to the arm of the machine and a bearing in which thefan and bandwheel are secured. Fig. 4c is a detail View showing theframe containing the gearing part of my device clamped to the table of amachine instead of being screwed thereto.

My invention is described as follows:

Fig. 1 represents the rear elevation of a high-arm sewing-machine, inwhich 1 represents the arm; 2, the plunger-frame; 3, the plunger; 4, theneedle-holder; 5, the bandwheel; 6, the band; 7, the balance-wheel, and8 the standard by which the machine is secured to the table. Mounted onthe table and in rear of the standard 8 is a framework 9, which may bedescribed substantially as an inverted U with one arm shorter than theother. This U is provided with perforated feet 10, through which it issecured to the table by means of screws 11. Secured mid- Way the longarm of this frame 9 is a bearing 12,in which is journaled an axle 13. Onthe left-hand end of this axle 13 is journaled a grooved pulley 14,against which the band 6 runs and rotates it. This band 6 may run oneither side of the pulley. 1n the drawings it is represented, however,as running on the near side or that side which is nearest the machine.This pulley 14 is secured rigidly on the end of the shaft 13 by means ofa thumb-nut fan to run I loosen this thumb-nut and then 15; but when 1do not want the this pulley 14C becomes an idler. On the right-hand endof the shaft 13 is a bevel gearwheel 16, which meshes with a bevelgearwheel 17, secured on a shaft 18, journaled in the lower end of theshort arm 19 of the U- shaped frame 9. The shaft 18 of the bevelgear-wheel 17 passes through the lower end of the short arm 19, and onthe rear end thereof is rigidly secured a band-wheel 20.

Secured to the arm of the machine near the plunger-frame 2 is a clamp21, having extending from it two projections 22 and 23, and throughthese projections runs a thumb-screw 24, by which the said clamp issecured to said arm. Secured to the lower projection 23 of the clamp 21is an elbow-arm 25, and to the upper end of this arm 25 is journaled anaxle 26, and on the front end of this axle 26 is rigidly secured a fan27, and on the rear end of said axle is rigidly secured a pulley 28. Aband 29 runs over the band-wheel 20 and the pulley' 28.

The operation of the fan is apparent, but may be described briefly bysaying that when the machine is in motion the band 6 of the machineoperates the pulley 14:, which in turn operates the mechanism described,which is secured to the table, the band-wheel 20 of which runs thepulley 28, which pulley, operating the shaft 26, runs the fan 27. When Ido not wish the fan to go, 1 loosen the thumbnut 15.

Having described my invention, what 1 claim as new, and desire to secureby Letters Patent, is

A frame 9, in the shape of an inverted U, secured to the table of asewing-machine, in rear of its standard 8; a shaft 13, journaled on aline with the arm of the sewing-machine to said frame; a pulley 14E,secured un the end of said shaft, in a line with the machine-band 6, andadapted to be operated thereby; a thumb-nut 15, working on the end ofsaid shaft 13, and adapted to hold said pulley rigidly in place; a bevelgear-wheel 16, rigidly secured on the other end of said shaft; a bevelgear-wheel 17, meshing with said bevel gear-wheel 16, and secured on theend of an axle 18; an axle 18, journaled in the lower end 19, of theframe 9 3 a band-wheel 20, rigidly secured on the rear end of the 'IOOshaft; 18; a clamp 21, secured around the arm 1; an elbow-arm 25,secured to said clamp, and extending backwardly and upwardly; a

shaft 26, journaled to the upper end of said arm; a pulley 28, securedto the rear end of said shaft; a, fan 27, secured to the front end ofsaid axle, and a band 29, Working around the band-Wheel 20, and thepulley 28, substantally as shown and described and for the purposes sebforth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM C. NORMAN.
